The Template plugin is easy to implement (check further down and documentation), but by default the template is inserted where the marker is. And I wanted the template to be added at the end of the document.

I looked into adding a new “insert after”-button on template-plugin UI, but that wasn’t doable.


Tag the html-templates and use the BeforeSetContent-event to hi-jack the pipe with your logic.

So, in the HTML templates I did start with a data attribute “<div data-insertafter” meaning it should have that behavior.

Template example:

<div data-insertafter class="tmpl1">
    <div class="padding">
        <h2>Template 1</h2>
        <p>Fusce accumsan ligula at dolor vulputate malesuada.</p>
  1. Implement the standard template plugin
  2. Register a custom plugin in tinymce.PluginManager
"use strict";
var tinymce = tinymce || {};
tinymce.PluginManager.add('insertaftertemplate', function (editor, url) {

    editor.on('BeforeSetContent', function (e) {
        if (e.content.include("<div data-insertafter")) {

            editor.setContent(editor.getContent() + '<div class="row"></div>');
            editor.selection.select(editor.getBody(), true);

            e.content = e.content.replace("data-insertafter", "");

    return {
        getMetadata: function () {
            return {
                name: 'Insert after for Templates', url : 'https://devblog.gosso.se/?p=847'


How to implement Template Plugin

All you need is …

1. add the source code to page

<script src=”/tinymce/js/tinymce.min.js”></script>
<script src=”/ClientResources/Scripts/tinymce/plugins/template_insert_hack/editor_plugin_v4.js “></script>

2. configure the template plugin

  selector: "textarea",  // change this value according to your HTML
  plugins: "template insertaftertemplate", //
  menubar: "insert",
  toolbar: "template",
  templates: "/dir/.../templates.htm" //json file

I choose to configure the templates in external file with json format “template.htm”

{"title": "Template 1", "description": "inserting inline", "url": "/ClientResources/Scripts/tinymce/plugins/template_insert_hack/tmpl1.htm"},
{"title": "Template 1 (after)", "description": "Inserting after", "url": "/ClientResources/Scripts/tinymce/plugins/template_insert_hack/tmpl1a.htm"},
{"title": "Template 2", "description": "inserting inline", "url": "/ClientResources/Scripts/tinymce/plugins/template_insert_hack/tmpl2.htm"},
{"title": "Template 2 (after)", "description": "Inserting after", "url": "/ClientResources/Scripts/tinymce/plugins/template_insert_hack/tmpl2a.htm"}

Register in a custom plugin in Episerver

With package Episerver.Cms.Tinymce v2 and later, you use TinyMceInitialization like this:

using EPiServer.Cms.TinyMce.Core;
using EPiServer.Framework;
using EPiServer.Framework.Initialization;
using EPiServer.ServiceLocation;

namespace Gosso.Mvc.Business.Initialization
    public class CustomizedTinyMceInitialization : IConfigurableModule
        public void Initialize(InitializationEngine context) { }

        public void Uninitialize(InitializationEngine context) { }

        public void ConfigureContainer(ServiceConfigurationContext context)
            context.Services.Configure<TinyMceConfiguration>(config =>
                    .AddSetting("template_popup_width", 1100)
                    .AddSetting("templates", "/ClientResources/Scripts/tinymce/plugins/template_insert_hack/templates.htm")
